The present invention relates to alock particularly for revolving doors inbanks, jewelry stores and other'establishments; and has for its primary object to provide, n a 6 manner as hereinafter set forth, a lock which is electrically actuated and controlled from remote points for frustrating; attemptsmat robberies by hold-ups orgother methods. V 3 Another important object of the invention" tioned character which, in operative or locked position, can only be released bypersons at apredetermined remoteclocation, such as a police station, etc.

Located on the support 2 adjacent opposite sides of the electric motor 16 are motor control switches 19 and 20 which are preferably of the toggle or lever type. When the switches 19 and 20 are in the positions shownfin- Figure 5 of the drawings, the switch 19 is'open and the switch 20 is closed. A horizontal v rod 21 is slidably mounted in bearings 22 which areprovided therefor and said rod21' extendsabove the motor shaft 17 and has its ends adjacent the switches 19 and 20. The shaft 21 is operatively connected to the switches 19 and 20 through the medium of yokes 23 which are'fiXed on the end portions of said shaft. It will thus be seen the shaft 21 is shifted inrone direction, the switch 19 will be opened and the switch 20 willbe closed and when said'shaft '21 is shifted in the opposite'direction, the

switch 19 will be closed and the switch 20" will be'opened.

Depending from spaced points on the shaft 21 are'arms 24 and 25 between the lower ends of which extend a connecting rod26. The arms 24 and 25 are'operatively engageable by a cam 27 which is fixed onthe motor shaft 17 between the motor 16' and the cam 18.

i A manually operable switch 28, preferably of the push button type, is interposed in the electric circuit between the switch 19 and the source of current supply- Any desired numberof the switches 28 maybe provided at s'uitablepoints in the bank or other establishment. The switc'h 28 is normally open. Alsointerposed in the electric circuit tothe switch 19 is an electric signal in theform of a bell 29; Of course, any other form of elecerative position. The clutch 9 engages the tric signal may be'provided.

Interposed in the electric circuit between theswit'ch 20 and the source of current supply is a normally open switch 30 which alsofis preferably of the push buttontype'. The switch 30 is preferably locatedat a point remote'from the bank or other establishment, asin a police 'station.

In use, when the sw tch 28 is closed, electric 'currentfiows through the switch 19 and energiz'es the motor 16, rotating, the cam 18 a fraction of a revolution to permit the shaft '12 and the yokes 13 and 14to drop, thus permitting the clutches 9 and 4 to move to opclutch 4 and said clutch 4 engages the clutch 11, thus locking the revolving door 1. Immediately after-this occurs, the cam 27 engagesthe cam 24 andshifts the shaft 21 in az-manner to open the switch 19 and simultaneously to close the switch 20, thus breaking the flow of electric current to the motor 16.

thereby.

Of course, so long as the switch 28 is closed, the signal 29 is energized.

To unlock the door, the switch 30 must be closed at which time electric current will flow through the switch 20 to the motor 16, there by energizing and actuating said motor. The cam 18 then raises the shaft 12 to lift the clutches 9 and 4 to inoperative position through the medium of the yokes 14 and 13, respectively. The cam 27 then engages the arm 25 and shifts the shaft 21 in an opposite direction for-opening the switch 20 and again closing the switch 19. .l/Vhen the switch 20. is opened, the flow of current to the motor 16 is again interrupted. The switches 19 and 20 are mounted on suitable supports 31 and 32-, respectively. 7

It is believed that the manyadvantages of a door lock constructed in accordance with the present invention will be readily understood, and although the preferredembodi ment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed. r 1

What is claimed is 1 1. A door lock comp-rising a shaft fixed to the door for rotation therewith, a clutch mounted-on the shaft for rotation withsaid shaft, a clutch engageable with the first named clutch for retaining-said first named clutch against rotation, an 1 electric motor, and means" operatively connecting one of the clutchesto the electric motor for actuation thereby, said means including acam mounted on the motor shaft, a slid'ably mountedshaft, an arm fixed on the slidable' shaft anden gageable bythe cam for actuation thereby, and a yoke operativelyconnecting said one clutch to the 2. door lock comprising ashaft fixed to the door for rotation tl1erewith,-'astationary clutch encircling the shaft, I double clutch splined' on theshaft and engageable, at one end, with the stationary clutch, a slidably mounted clutch engageable with the double clutch for retaining the same against rotation, an electric motor, and means open atively connectlng the second and third named clutches to the electric motorforactuation.

to inoperative position thereby.

3. Adoor lock comprising a shaft fixed to the door for rotation therewith, a stationary clutch encircling the shaft, a'double clutch splined onthe shaft and engageable, at one end, with the stationary clutch, a slidably mounted 'cl'utch"engageab1e'with the. double F clutch for retaining thesa'me against rotation, an electric motor, and means operat ively connecting the secondand third named-clutches to the electri'c motor for actuationto inoperative'position thereby, said means includ slidable shaft for actuation ing a cam mounted on the motor shaft, a slidable shaft, an arm fixed on the slidable shaft and engageable with the cam for actuation thereby, and yokes fixed on the slidable shaft 5 and engaged with said second and third named clutches for connecting the same to the slidable shaft for actuation thereby.

In testimony whereof we a'fiix our signaturee.
